How does AI-powered people tracking technology upgrade existing Video Surveillance Analytics system?


In large public places such as shopping malls, airports, and train stations, various criminal incidents often occur, including cases such as the elderly or children getting lost, robbery, theft, and other crimes. The harm and pain caused to the victims and their families by these incidents are unimaginable. Therefore, security guards are increased to patrol these public places or surveillance cameras are installed to monitor them.

However, simply using existing surveillance cameras, video management systems, or video surveillance analytics software may achieve partial prevention or monitoring objectives, but there are still many drawbacks. For example, the large number of surveillance cameras in public places, such as shopping malls, airports, or stations, means that security personnel have to retrieve every surveillance video and carefully review the footage from each camera in order to identify suspicious individuals or missing persons manually. This process incurs a significant amount of labor cost and time, and cannot provide real-time and effective crime alerts or missing person assistance.

Therefore, a new generation of AI-powered people tracking technology is integrated into the existing video surveillance analytics system. It can automatically recognize human body shapes and clothing, and track specific individuals based on characteristics such as age, gender, clothing, and accessories. This enhances the effectiveness of the existing video surveillance analytics system, making the entire search and analysis process more precise and efficient.

Video Surveillance Analytics system vs. People Tracking Technology

What’s Video Surveillance Analytics?

Video Surveillance Analytics system is a system that uses computer vision technology to capture and analyze images from surveillance cameras to detect, recognize, and analyze people, events, and behaviors. Generally, these systems are also able to store vidoe for long periods of time for subsequent queries and analysis. Video Surveillance Analytics systems have been adopted in various industries, including law enforcement, transportation, retail, healthcare facilities, hotels, and manufacturing, and they provide valuable analysis information to enhance security by detecting threats, preventing crime, and improving situational awareness.

When AI technology is incorporated into video surveillance analytics systems, it can automatically analyze surveillance video without the need for human monitoring and actively alert guards or security personnel to abnormal situations through alarm notifications. Incorporating AI technology can bring several benefits to video surveillance analytics systems, including: higher accuracy, faster response time, savings human resources and costs, ability to handle more complex environmental conditions, and increased sense of security in people's lives.

What’s People Tracking technology?

People Tracking technology is a technique for tracking and analyzing individuals in surveillance footage, typically using AI video analysis algorithms to identify human body contours and features. By tracking and analyzing the movement patterns of contours and features, it can accurately track information such as the selected individual's location, movement speed, and direction. Its main purpose is to identify and analyze the movement patterns of individuals, understand their activity range, movement routes, and behavioral patterns, and further conduct crime prevention, tracking, or searching for missing persons.

People tracking technology can be widely used in fields such as public safety and smart cities. For example, in places with high people traffic such as office buildings, large shopping malls, public spaces, airports, subways, or stations, people tracking technology can be used to enhance public safety and assist in locating missing persons.

How can People Tracking technology improve the performance of Video Surveillance Analytics system?

Adding people tracking technology to the video surveillance analytics system can further improve the overall system performance. Specifically, there are several applications:

  1. Improved recognition rate: Adding people tracking technology to the video surveillance analytics system can improve the recognition rate of tracking people trajectories. Through AI video analysis, filtering can be done based on conditions such as the age, gender, appearance, clothing, backpacks, etc. of the tracked person, allowing the system to more intelligently and accurately identify people, thereby reducing the false recognition rate and minimizing false alarms.
  2. Improved crime detection capability: People tracking technology can assist law enforcement in crime detection and tracking by analyzing information such as the movement path and activity range of individuals. For example, if a person stays in a specific area for too long or repeatedly visits the same location, this may indicate suspicious activity. In robbery or theft incidents, the system can assist law enforcement in quickly locating the possible whereabouts of suspects by tracking their movements, increasing the success rate of arrests.

What AI technologies are included in People Tracking technology?

1. Person Re-identification

Person re-identification use full-body images to track and find the same person across different cameras. It involves matching individuals in different cameras based on appearance or other features, such as clothing, height, or gait.

In a typical person re-identification system, a camera initially detects and tracks a person, and the system then uses this information to match the same person in other cameras. Due to differences between different camera, as well as the rigid and flexible characteristics of people, appearance can be easily affected by clothing, scale, occlusion, posture, and viewpoint, making people re-identification a challenging and popular topics in the field of computer vision.

To overcome various challenges, person re-identification systems use advanced AI algorithms and technologies such as feature extraction, metric learning, and deep neural networks, which enable the system to extract unique features from a person's appearance and compare them across different cameras. Person re-identification has numerous applications in video surveillance, such as tracking suspects in large public spaces or identifying lost children in crowded areas.

2. Person Attribute Recognition

When security personnel do not have a pre-existing image of a person but have knowledge of their attribute characteristics (such as gender, age, clothing, or accessories), person attribute recognition technology can be used to track the person in surveillance footage. Person attribute recognition technology uses deep machine learning to extract features from image and then identifies specific attributes related to individuals (such as gender, age, clothing, or accessories), thereby finding persons in surveillance footage that match those conditions and helping to identify suspects or lost children.

3. Face Recognition

In people tracking technology, facial recognition refers to the technique of identifying people by recognizing their faces captured by cameras.

By integrating FaceMe® facial recognition engine, facial photos can be inputted for more accurate tracking of target individuals. Extraction and matching of facial features of people enable identification and tracking of the same person across different cameras. In practical applications, facial recognition technology can be used to enhance people re-identification, security and other aspects. For example, in surveillance systems, when suspicious behavior occurs, facial recognition technology can be used for more accurate investigation and tracking of potential suspects.

Face recognition can make tracking of target individuals more accurate.

What features should a complete People Tracking solution include?

A complete people tracking solution should integrate the three AI technologies mentioned above: person re-identification, person attribute recognition, and facial recognition. Through the integration of these three technologies, people can be identified and tracked more accurately, and further identity information can be obtained. Person attribute recognition technology can identify the appearance characteristics of people, such as gender, age, height, clothing, and accessory information, to initially locate the image of the people to be searched, which can be used by person re-identification technology to track the people under different cameras. Finally, if facial recognition technology is added, the overall people tracking can become more detailed and accurate.

In addition to possessing the three AI technologies mentioned above, a complete people tracking solution should also have the following two features:

  1. Cross-camera tracking capability: The ability to track people across multiple cameras is one of the important features of people tracking. In public places, cameras are usually deployed in different locations to provide complete coverage of the monitoring area. However, this deployment method also poses a challenge to people tracking technology. Therefore, in order to make cross-camera people tracking more accurate, a powerful algorithm is needed to track people movement and identify their identity.
  2. Integration with mainstream Video Management Systems (VMS): Integration with mainstream video management systems is essential for a complete AI-powered people tracking solution. It enables automatic analysis and identification of a large number of surveillance footage. Existing VMS systems can integrate with multiple cameras and provide a unified management interface for surveillance managers. Once integrated with AI-powered peopletracking functionality, surveillance managers can easily upgrade their existing systems without the need to learn a new system. This allows for real-time video analysis and quick post-event search, making it a painless upgrade to existing video surveillance management systems and creating a more convenient and user-friendly peole tracking functionality.
